SOLDERING-IRON.

SPECIFICATION forming' part of Letters Patent N0. 541,210, dated June 18, 1895. v

Application led June 21,1894. Serial No. 515,319. (No model.)

.To all whom it may concern:

Be it known that I, ROBERT MCSHANE, a citizen of the United States, residing at Winona Springs, in the county of Carroll and State of Arkansas, have invented certain new and useful Improvements in Soldering-Irons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specilication.

My invention relates to an improvement in soldering irons; and it consists in a shank, having a suitably bent end, and a detachable copper bit, combined with a recessed iron block which slides back and forth on the shank, and means for locking it in position on the bit, as will be more fully described hereinafter.

The object of my invention is to heat the detachable bit by means of aniron block which is recessed so as to tit over the rear end of the bit, and which slides back and forth on the shank, the block being heated while the bit is removed from the shank, and then forced over the end of the bit after it has been returned to position, thus preventing the necessity of having to put the bit in the tire.

In the accompanying drawings, Figure l is a perspective of a soldering-iron which embodies iny invention. Fig. 2 is a vertical section of the same, the handle being removed. Fig. 3 is a vertical longitudinal section of the iron block alone. Fig. 4 is a perspective of the copper bit. Fig. 5 is a vertical longitudinal section of the inner end of the shank.

E represents an ordinary handle, and C the shank secured thereto, and which has its inner end 2 formed or bent at an angle so as to lit in,V a correspondingopening through 'the copper bit B. This bit is of the usual construction, and in addition to having an opening extending at right angles through its inner end, it has the longitudinal groove B3 in one side, extending from the hole to the end, so as to receive the portion of the shank adjacent tothe end 2, as shown in Fig. 2. When the shank is applied to the bit, the outer edge of thewshank is just flush with its outer edge, so that the recessed sliding'iron block A will 'fit snugly over and secure them together. The iron block A, as shown in Fig. 3, has a central recess, large enough to tit over the ends of the bit and shank, and extending from this recess through the rear-end of the block, and eccentric to the center of the recess is an opening through which the shank passes.

When the bit is inserted into the tire, it is apt to become overheated and thus burn both the bit and destroy the tinning upon it. To prevent this the iron block is to be heated and then moved over the end of the bit, the heat of the block serving to heat the bit and to keep it hot for a longer time than could be done if the bit alone were heated in the usual manner. When the block is to be heated the locking collar D is loosened by means of its setI screw D from the shank, and then the collar and block are moved backward on the shank far enough to allow the bit to be detachedfrom the shank. The blockvis then moved forward to the end of the shank, and thrustinto the tire. When heated sufciently, the block is moved backward on the shank, the bit is attached, and then the block is moved forward over its rear end, as shown in Figs. l and 2, and locked in position by the collar D and set screw D. The bit being only heated indirectly, its point is not injured by being burned, and the tinning on its point is not being constantly destroyed.

' Having thus described my invention, I

The detachable bit, a lshank having a suitably bent end for attachment to the bit, and a separate iron block provided with a hole through which the shank is adapted to pass, said block being capable of longitudinal adjustment on said shank, said block being also providedwith a recess which enables it to be applied over the inner end of the bit, when the bit 1s attached to the shank and substantially envelop the body thereof, the parts be# ing combined and arranged to operate, substantially as set forth. v Y

In testimony whereof I altix my signature in presence of two witnesses.

ROBERT MCSHANE. Witnesses:
